Forefoot relieving shoe, more particularly for postoperative treatment

Abstract

For ensuring longer wear or utilization times without damage to the walking block, the sole portion (11) of the forefoot relieving shoe, more particularly for the postoperative treatment, with a different sole portion elasticity and with a sole portion (11) which is substantially triangular in a side view or in a vertical longitudinal cross-section and possessing a thickness which diminishes toward the rear and which terminates before the metatarsal region of the wearer, of a homogeneous foamed plastic (19), wherein a spring (20, 21) is embedded which can be tensioned against the pressure exerted by a foot on the shoe.

What is claimed is: 
     
       1. A forefoot relieving shoe for a foot having a metatarsal region and a calcaneal tuberosity, the forefoot relieving shoe having a longitudinal direction and a front and a rear, the forefoot relieving shoe comprising a single-piece sole portion having an essentially triangular cross-section in the longitudinal direction, the sole portion having an upper side, wherein a thickness of the triangular sole portion decreases toward the rear, and wherein the sole portion ends before the metatarsal region, the sole portion comprising a homogeneous foamed plastic body, a supporting carrier plate projecting toward the front from the triangular sole portion, a leaf spring embedded in the sole portion so as to be flush with marginal areas of the upper side of the sole portion, the leaf spring having a bottom side, further comprising a curved spring having an anterior leg and a posterior leg, and a front flat section connected to the anterior leg and a rear flat section connected to the posterior leg, wherein the front and rear flat sections of the curved spring are attached to the bottom side of the leaf spring, the anterior leg extending essentially parallel to a sole portion front face located adjacent the supporting carrier plate and perpendicular to the upper side of the sole portion, and the posterior leg extending at an angle of between 35° and 55° relative to the upper side of the sole portion, wherein the front flat section of the curved spring is located in a transition area between the support carrier plate and the triangular sole portion, and the rear flat section is located a short distance in front of the calcaneal tuberosity. 
     
     
       2. The forefoot relieving shoe according to claim 1, wherein the leaf spring extends essentially over an entire length of a sole of the shoe. 
     
     
       3. The forefront relieving shoe according to claim 1, wherein the triangular sole portion has a compressibility which increases from the rear toward the front. 
     
     
       4. The forefoot relieving shoe according to claim 1, wherein the curved spring is of a flat material having at least one perforation, the foamed plastic body extending through the perforation. 
     
     
       5. The forefoot relieving shoe according to claim 4, wherein the perforation has a longitudinally oval cross-section. 
     
     
       6. The forefoot relieving shoe according to claim 1, wherein the leaf spring has a perforation located in front of the front flat section of the curved spring. 
     
     
       7. The forefoot relieving shoe according to claim 1, wherein the posterior leg of the curved spring has a perforation. 
     
     
       8. The forefoot relieving shoe according to claim 1, wherein the leaf spring and curved spring are comprised of an elastomeric plastic.
